Ethos Green Power Cooperative

Each mark is one company we hold in Wisconsin whose Google breakdown has been read, placed by its share of one and two star reviews. Ethos Green Power Cooperative is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

  I needed some repairs done to my system. I talked to them and was told they would get right back to me. It took more calls from me and some time for them to call me back and then they told me they did not want to do the work. I wasted a week which could have been avoided if I just got a quick return call. Little annoying - no idea about how well the work they do is.

  Highly recommend Ethos Green Power Cooperative to anyone considering solar systems ! Having bought a home with an existing solar system, we had no experience or knowledge about it. Ethos was wonderful to work with and 100% helped us to understand and feel comfortable with it. Shoutouts to Bob for his great explanation and lessons and Brad for his skilled help in maintenance of the unit. We love the savings our solar provides and appreciate how welcoming Ethos has been , thank you!

  I worked with Matthew, Clovis, and Emily (forgive me for missing others' names) to get my system expanded. They were all easy to work with, and super patient with my many questions. I am so happy with my set up and especially the monitoring capabilities. My only complaint is on me....I should have done this earlier!

  They installed our solar array & heat pump and both experiences were easy and timely. They communicated through every step so we had no surprises. All the staff and crew are friendly and helpful!

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

• Google also lists this company under heating and cooling.
• It is also reviewed on the Better Business Bureau. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

• —The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
• —We found nothing on a website for this company that states a warranty, a licence or how long it has traded.
• —We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
• —We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
